我在启动时在程序中初始化报告时遇到问题。前段时间,它工作正常。但是当我将 JDK 1.7 更新 17 卸载到 JDK 1.7 更新 21 并全新安装 Netbeans 时,异常存在:(
这是错误消息:

这是我初始化报告的代码。
public void initReport() {
try {
param.put("noMr", "0000");
param.put("visitCode", "V-199208300000");
param.put("templateLoco", iReportDir);
param.put("tools", "Tools");
param.put("medicine", "Medicine");
param.put("result", "Data hasil disini");
param.put("conclusion", "Data kesimpulan disini");
param.put("suggestion", "Suggestion");
param.put("SUBREPORT_DIR",iReportDir);
String imageLoco = iReportDir +"image-sample.jpg";
for (int i = 0; i < 20; i++) {
FileInputStream image = new FileInputStream(imageLoco);
param.put("imgResult"+(i+1), image);
}
param.put("emptyImg", iReportDir+"logo.jpg");
setTemplate("data/reports/templates/template_1.jasper");
jasperPrint = JasperFillManager.fillReport(getTemplate(), param, DatabaseUtility.getConnection());
} catch (JRException ex) {
System.out.println(ex.getMessage());
} catch (IOException ioe) {
System.out.println(ioe.getMessage());
}
}
但是,当我构建到。罐子,错误消失了。
请帮忙,谢谢之前:)
